The Wealth of Nations_ Books 4-5 - Adam Smith [281]
What are called poll-taxes in the southern provinces of North America, and in the West Indian Islands annual taxes of so much a head upon every negro, are properly taxes upon the profits of a certain species of stock employed in agriculture. As the planters are, the greater part of them, both farmers and landlords, the final payment of the tax falls upon them in their quality of landlords without any retribution.
Taxes of so much a head upon the bondmen employed in cultivation seem anciently to have been common all over Europe. There subsists at present a tax of this kind in the empire of Russia. It is probably upon this account that poll-taxes of all kinds have often been represented as badges of slavery. Every tax, however, is to the person who pays it a badge, not of slavery, but of liberty. It denotes that he is subject to government, indeed, but that, as he has some property, he cannot himself be the property of a master. A poll-tax upon slaves is altogether different from a poll-tax upon freemen. The latter is paid by the persons upon whom it is imposed; the former by a different set of persons. The latter is either altogether arbitrary or altogether unequal, and in most cases is both the one and the other; the former, though in some respects unequal, different slaves being of different values, is in no respect arbitrary. Every master who knows the number of his own slaves knows exactly what he has to pay. Those different taxes, however, being called by the same name, have been considered as of the same nature.
The taxes which in Holland are imposed upon men- and maid-servants are taxes, not upon stock, but upon expense, and so far resemble the taxes upon consumable commodities. The tax of a guinea a head for every man-servant which has lately been imposed in Great Britain is of the same kind. It falls heaviest upon the middling rank. A man of two hundred a year may keep a single man-servant. A man of ten thousand a year will not keep fifty. It does not affect the poor.
Taxes upon the profits of stock in particular employments can never affect the interest of money. Nobody will lend his money for less interest to those who exercise the taxed than to those who exercise the untaxed employments. Taxes upon the revenue arising from stock in all employments where the government attempts to levy them with any degree of exactness, will, in many cases, fall upon the interest of money. The Vingtième, or twentieth penny, in France is a tax of the same kind with what is called the land-tax in England, and is assessed, in the same manner, upon the revenue arising from land, houses, and stock. So far as it affects stock it is assessed, though not with great rigour, yet with much more exactness than that part of the land-tax of England which is imposed upon the same fund. It, in many cases, falls altogether upon the interest of money. Money is frequently sunk in France upon what are called Contracts for
